Positive feedback to one of the nulling terminals creates

approximately 5

µV of hysteresis. Output can sink 16 mA.

Input offset voltage is typically changed less than 5

µV due to

the feedback.

The addition of the LT1007 doubles the amplifier’s output drive

±33 mA. Gain accuracy is 0.02%, slightly degraded

compared to above because of self heating of the LT1037 under

load.
